System for electronically controlling LED-array image printer

摘要

A system for controlling an image printer including a scanning LED array is provided. An image printer control unit receives page profile and raster image data and converts the raster image data into parallel image data corresponding to the configuration of the LED array. Advantageously, the image printer control unit optimizes the number of lines of information printed during a scan to reduce splitting of characters between scans and coordinates printhead and photosensitive medium position. Interlaced scanning for high resolution is also provided. In an alternative embodiment image data is received in parallel vertical slices and bands for which no exposure is to be made are skipped.
